CNAME is short for canonical name, also referred to as a CNAME record, a record in a DNS database that indicates the true, or canonical, host name of a computer that its aliases are associated with.<\/p>\n
CNAME-records can be used when a computer or service needs to be renamed, to temporarily allow access through both the old and new name.<\/p>\n
1. A CNAME-record should always point to an A-record and never to itself or another CNAME-record to avoid circular references:<\/p>\n
In the following example, an A record binds a hostname to an IP address, while a CNAME record points the commonly used www hostname to it:
\nserver1 IN A 10.0.1.5
\nwww IN CNAME server1<\/p>\n
2. Often a CNAME is used to point a subdomain to another domain. Here is an example of a CNAME:<\/p>\n
www.toolbaz.com. IN CNAME eric.toolbaz.com.<\/p>\n
Example: to point www1.mydomain.com to point to<\/p>\n
www.mydomain.com:
\nSubdomain to enter: www1
\nCNAME to enter: www<\/p>\n
Result: Browsing to www1.mydomain.com would render the same page as www.mydomain.com<\/p>\n
3. One of the times where CNAME records can be useful is when you want a subdomain to point to a computer outside of your domain. For example, you might want “news.example.com” to go to your ISP’s newsserver. Instead of putting in the IP address, you could put configure the following:<\/p>\n
Subdomain to enter: news.example.com<\/p>\n
CNAME to enter: news.myisp.com<\/p>\n
That way if the IP address of the newsserver changed, you wouldn’t have to make any changes.<\/p>\n
4. Another simple example of CNAME is when you wish to mask your domain:<\/p>\n
Example: To point www.yourdomain.com to another website while maintaining www.yourdomain.com in the address bar of the browser:<\/p>\n
Subdomain: to enter: www
\nCNAME to enter: www.anotherdomain.com<\/p>\n","protected":false},"excerpt":{"rendered":"
